Be it known that I, ANTHONY J'. IIINDERMEYER, of Rohrcstown, in East Hempfield township, Lancaster county, and State of Pennsylvania, have invented a new and improved Mode in the Manufactureof Steel-Gapped Rails for Railroads; and I do hereby decla-re that the following is a full and exact description thereof. Reference to the accompanying drawings, making a part of this specification, will aid in more clearly understanding the same, in which Figure 1 shows an ordinary pile of iron plates, with the steel plate A on top.

Figure 2 shows a similar-pile, with the addition of steel bars B under the plate A, being a second process.

Figure 3 shows the steel-capped rail resulting from my first process.

Figure 4, the stecl-capped rail resulting from my second process.

Figure 5 shows a pile set edgewise preparatory to joining the steel` plate A.

Figure 6, a portion of a rail shown in perspective.

The nature of my invention consists in the manner of manipulating, in order to produce a thorough union of the steel plate, or plate and bars, with the iron platcsjpreparatory to being rolled into the desired form or shaped rail by any of the machinery now in use. Y

To enable others skilled in the art to use my improved mode or process, I will new describe more fully.

I construct my pile in thc usual manner for heating in the furnace, composed of tbedesired number of iron plates. In vthe mean time, in a separate side furnace, I-hcat my steel plate A.V The `furnaces may be charged with six of these piles and separate plates at a time. When brought to awclding heatrI draw a plate of steel, A, lay itin a proper position, so that when my patent flux is applied te the top of the pile and plate, by turning the pile on its edge, as shown by tig. 5, with a paddle and quick motion I raise the steel plate'A, so as to come in contact with the top plate s of the piles, (shown by the dotted lines,) being of the same size, brings the iuxed faces in close and equal contact. I new turn 'the pile with the steel plate A, beneath cr on the hearth-bed, in' order to heat the sides for thelangcs thoroughly without injury to the steel plate. I then turn the pile to bring the steel plate on top, when I apply another coat of linx to protect the steel plate from being burned. When the same is brought to a yellow heat, I draw the pile, and submit it to the ordinary machinery for rolling out, which results in producinga steel-capped rail, shown by iig. f3.

My second process diifers only in forming the top layer of the pile, by introducing two steel bars B, slay' one inch square, with au iron inch bar between them, inthe centre of the pile, and a two-inch bar on the outer side of each, as shown by iig. 2. I apply my tlux to thc steel bars both for the purpose oftluxing and protecting the steel, being heated together with the other plates 'forming the Vpile, the steel plate A being, however, separately heated and worked on to the pile, as in my first process, and rolled out, which results in forming therail, as shown by figs. 4, 6.

I am aware that S. L. Potter, Superintendent of the Wyandotte Rolling-Mills, claims tohavc discovered a plan by which a pile can be made of iron and steel, and disposed in suchamanner that theifon 'will receive twice as much heat in thefurnace as the steel, consequently both brought up to a welding heat at the same time, without injuring the properties of either. Be this as it may, I find it safer and giving more satisfactory results by heating the steel in a separate furnace for the steel cap or top plate. Besides, he introduces a billet of live by four inches thick, having been previously rolledor hammered from ingots seven or eight inches square, which he introduces into` the side of the ordinary rail pile. When worked oif it forms a wedge-shaped head, extending partially into the shank, thereby weakening it greatly at a very essential point. I am also aware that Patent No. 60,723 claims a steel-headed rail, by workingin a corrugated steel bar; bot-h of' which methods I disclaim.

What I claim as my invention, and desire to secure by Letters Patent, is- The method herein described of constructing, iluxing, and heating a pile ef iron and steel bars, to be suhsequently converted into a railroad rail by rolling, as set forth.
